Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

www.iso.org/iso/foreword.html.

This document was prepared by Technical Committee ISO/TC 96, Cranes, Subcommittee SC 6, Mobile

cranes.

This second edition cancels and replaces the first edition (ISO 11661:1998), which has been technically

revised.
The main changes are as follows:
— added 6.5 for manuals in electronic form;
— re-labelled items in Annex A as examples.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www.iso.org/members.html.

Mobile cranes — Presentation of rated capacity charts
1 Scope

This document specifies a standard presentation or format for mobile crane rated capacities on rated

capacity charts.

It is applicable to mobile cranes fitted with boom and boom/jib combinations as defined in ISO 4306-2.

2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 4306 (all parts), Cranes — Vocabulary — Part 2: Mobile cranes
3 Terms and definitions

For the purposes of this document, the terms and definitions given in the ISO 4306 series and the

following apply.

ISO and IEC maintain terminology databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/

diagrams (3.3), allowable configurations, warning notes, and other information supplied by the

4 Crane rating manual
4.1 General

The crane rating manual shall be supplied with each crane and be available to the operator when at the

controls. The crane rating manual may be in electronic or physical form such as paper, plastic or metal.

When electronic form is supplied, an alternative method for referencing the crane rating manual shall

be supplied with the crane and shall be available to the crane operator for when the electronic system

is not functional.
4.2 Content of manual
4.2.1 Boom extend modes and configurations

The crane rating manual shall contain information necessary to identify and arrange the boom extend

mode configuration for each rated capacity chart. For cranes with only one boom extend mode, this can

be omitted.
4.2.2 Counterweight configuration

The crane rating manual shall contain information necessary to identify and arrange the required

counterweight configuration for each rated capacity chart. For cranes with only a fixed counterweight

(CTWT), this can be omitted.
4.2.3 Auxiliary equipment mass table

The crane rating manual shall include a table consisting of the equivalent deductions for all auxiliary

equipment that can be installed on the boom. When such equipment is installed, instructions shall be

provided if these tabulated values are to be subtracted from the rated capacities in the rated capacity

chart to determine the net available capacity. This table can be either at one place within the manual or

included with each applicable rated capacity chart.

Auxiliary equipment is any equipment provided by the manufacturer with an individual crane that can

be installed onto the crane except via the load hoist line (e.g. jibs). Equipment that is attached via the

load hoist line, such as hook blocks, shall be considered as part of the load subtracted from the printed

capacities on the chart. Illustrations, where deemed necessary, should accompany the mass table.

4.2.4 Working range diagrams

The crane rating manual shall include a working range diagram for each main configuration as

determined by the manufacturer (see Example A.3). The diagram can be located at one place within

the manual or as a corresponding diagram with each rated capacity chart on the opposite facing page.

For simple cranes, where all unloaded boom instability areas can be clearly shown on a single working

range diagram, it may be separately mounted and not included in the manual.
4.2.5 Forward stability

If forward stability limitations exist for any configuration in an unloaded condition, these limitations

shall be clearly defined along with any requirements. An unloaded condition at a given boom length/

angle is a condition where only the heaviest load block (e.g. hook block, overhaul ball) specified by the

manufacturer for the specific machine is attached to the crane via the load hoist line.

4.2.6 Backward stability

If backward stability limitations exist for any configuration, these limitations shall be clearly defined

on the working range diagram or on the specific rated capacity chart.

ISO 11661:2022(E)
4.2.7 Working area diagram

The crane rating manual shall include a working area diagram for which rating capacities apply. The

working area diagram can be either at one place within the manual or included with each applicable

rated capacity chart (see Example A.4).
